Its NOT a 'scam' as such, as if people were to action the email like it asks then yes you would get quite a bit of money from it.

I personally am very sceptical about pyramid games, which makes me think that loads of other people are too so why would it work.

However, I do know someone who did a pyramid game jointly with his Mum, they put in £2000 between them, and in the following months they got back about £10,000 from it.

To work tho, you have to be lucky in sending the email on to people who aren't sceptical........ which in this day and age is hard.
